Interactive touch screen displays and tables; links to Interactive Multimedia Technology and Tech Psych blogs

I have some information about touch-screen displays and tables on my Interactive Mutlimedia Technology and Tech Psych blogs.
Last semester, I spent some time working with applications for touch interfaces to support the collaboration between two or more people. I wanted to get my hands on a touch-table, but found that most tables were not yet available to the public.
One system, the Touch Table, had most of the features that I wanted, but the price at the time was $59,000.00!
Fortunately, less expensive screens are on the horizon. One of Microsoft's newest releases, Surface, is a touch-screen table that looks like it has many possibilities for the future. I understand that it will be released by November, 2007, and will cost between $5,000.00 to $10,000.00. This is still a bit expensive.
I would also like to see touch-applications embedded on adjustable surfaces, so that users can position them according to need, somewhat like an adjustable drafting table. They'd be great in classrooms.
What do you think?
